The big end of step 4, finish turning;
Step 5, finish turning small end;
Step 6, brill disk hole;
Step 7, ream counterbore;
Step 8, by product drawing inspection warehouse-in.
Preferably, described step 2 is to press from both sides positive cylindrical with three-jaw on numerically controlled lathe, on the basis of big end end face, carries out thick Car, detailed process is as follows: car small end end face, boring endoporus and the circular arc of end face, endoporus and end face, endoporus and correspondence and chamfering, presses Process chart slide gauge, depth indicator and R rule inspection.
Preferably, described step 3 is to stretch tight positive endoporus and end face with three-jaw on numerically controlled lathe, rough turn: car big end end face, Cylindrical and end face, cylindrical, boring endoporus and end face, endoporus and end face, endoporus and end face and the circular arc of correspondence and chamfering;By process chart With slide gauge, depth indicator, magnetic dial gauge and R rule inspection.
Preferably, described step 4 is to stretch tight positive endoporus and end face with three-jaw on numerically controlled lathe, finish turning: in car step 3 Each face, each dimensioned is to finished size;With slide gauge, outside micrometer, depth indicator, electronics height gauge, three coordinates Measuring instrument, inside diameter caliper and R rule inspection.
Preferably, described step 5 is to press from both sides positive cylindrical with three-jaw on numerically controlled lathe, on the basis of big end end face, and finish turning: Car small end end face, boring endoporus and the circular arc of end face, endoporus and end face, endoporus and end face, endoporus and correspondence and chamfering, each size It is machined to finished size;With slide gauge, outside micrometer, depth indicator, electronics height gauge, three-coordinates measuring machine, inside diameter caliper With R rule inspection.
Preferably, described step 6 is to use drill jig workpiece pressing in vertical machining centre, bores disk hole, by drawing control dish Hole location;With slide gauge, three-coordinates measuring machine inspection.
Preferably, described step 7 be on drilling machine with fixture by Workpiece clamping, counterbore in ream disk hole;Examine with slide gauge Test.
The most progressive effect of the present invention is: the present invention improves the machining accuracy of product, it is ensured that product quality, prolongs Grow service life, reduce use cost.
